, their relationship has been strained for nearly seven years.
But it is believed the families will settle their differences for the wedding, despite their past.
A menu which includes steak, salad, sushi and pasta has reportedly been leaked for guests to feast their eyes on.
Also a private jet flew in with Antonella's wedding dress from Spain, along with some of the most famous footballers in the world.
Messi will be joined by the likes of Xavi, Carles Puyol, Sergio Busquets and Jordi Alba as well as former Barca team-mate Cesc Fabregas.
Former Barcelona striker Samuel Eto’o was also pictured on the runway ahead of the wedding.
Messi met Roccuzzo when they were just 13 years old and the pair have two children together, named Thiago and Mateo.
One of his team-mates, Andres Iniesta has said he will not be able to attend the wedding, while Gerard Pique’s partner Shakira will be performing as part of the evening’s entertainment.
Messi chose not to invite former boss Luis Enrique and his assistant Juan Carlos Unzue.
Also no members of the Barca board were invited due to a long-running feud between former president Joan Laporta and current president Josep Maria Bartomeu.
